Unsupported Function Block Diagram instructions

The following FBD instructions are not supported:

VeriSign Universal Root Certification Authority certificate

If the VeriSign Universal Root Certification Authority certificate does not exist on the local computer, the certificate is installed while installing Rockwell Automation software. Use Microsoft Management Console (MMC) to view the certificate in Console Root > Certificates (Local Computer) > Trusted Root Certification Authorities > Certificates.

Unattended or silent install

Use command-line parameters to perform an unattended or silent installation of the software.

Command-line parameters

The following table identifies the installation command-line parameters. Command-line parameters are case-insensitive. However, if a specified value includes a space, be sure to enclose the value in quotation marks (for example, "value with spaces").

Parameter
Description
/?
Displays the usage options for installation parameters.
/Q
Silent Install, install runs in a quiet mode without any user interface.
This parameter is recommended if you are deploying the software installation using an IT tool or script, and don’t expect to see any error or restart messages. When using this parameter, your IT tool or script should check the error codes, and respond as needed. For example, if the installation returns error code 1641, then the IT tool or script should restart the computer and relaunch the installation after restart.
This parameter is required if /QS or /Record is not specified.
/QS
Unattended Install, install runs in a quiet simple mode and shows progress through the UI, it does not accept any input but still shows error or restart messages.
When using this parameter, you will not have to check the error codes, and the installation will stop and display a prompt if there are error or restart messages. For example, if an immediate restart is required to complete the install, a restart message will be displayed for you to confirm the restart. Installation resumes automatically from the point of interruption after restart.
This parameter is required if /Q or /Record is not specified.
/IAcceptAllLicenseTerms
Acknowledges acceptance of the license terms.
This parameter is required for /Q or /QS parameters.
/AutoRestart
Automatically restarts the computer after the installation is complete. Used when a restart is required to complete the installation.
This parameter is optional. If this parameter is not used silent install (/Q) will return either error code 1641 or 3010 if a restart is required, and unattended install (/QS) will result in a confirmation prompt that must be agreed to before the installation is completed.
/SetupLanguage="value"
Specifies which language will be displayed during install process.
The value must be the one of the following:
  • ENU
  • CHS
  • DEU
  • ESP
  • FRA
  • ITA
  • JPN
  • KOR
  • PTB
This parameter is optional. If this parameter is not used, the default language is the current user or operating system user interface language.
/Record
Records the installation options chosen to a recording file.
This parameter is optional.
/Playback
Plays back a recording file to specify the installation options.
This parameter is optional.
/InstallLocation="value"
Specifies the install location.
This parameter is optional. If this parameter is not used, the default install location is "C:\Program Files (x86)\Rockwell Software".
Some software restricts the installer to only change the drive the software is installed on. Use /? to determine which parameter is supported.
/AddLogixMenuItem="value"
Adds Compare Tool as a menu command in the Tools menu of Logix Designer. This is supported for Logix Designer version 13.00 or later.
This parameter is optional. The default value is 0, which specifies that Compare Tool will not be added as a menu command. Values except for 0 specify that Compare Tool will be added as a menu command.
